Concern over the shipment of volatile Bakken crude oil following an explosive and deadly wreck last summer in Quebec led to a federal order in May, requiring railroads to provide information to states.

Prices at the pump have soared over the past month. Mike Fox, head of the Gasoline & Automotive Services Dealers of America in Connecticut, said the spike in prices is not due to a lack of crude oil or refined gas supplies.

At a time when gas prices typically rise, they are forecast to drop. “We saw the price of crude oil drop by $9 as of Monday, and that’s the highest one-week drop this year,” Robert Sinclair, Jr. of AAA said. “With it will come gasoline prices.”

In New Jersey, known for its cheap fuel, the average price per gallon for regular gas is now $3.61. In New York, it’s $3.96. Connecticut drivers have it worst, with the average price for regular at almost four dollars a gallon.
